Mussels filter large volumes of water and can concentrate pathogenic organisms, which may act as potential vehicles of transmission to the consumer. A survey study was carried out to investigate the presence of Cryptosporidium protozoan parasites in green mussels (Perna viridis), the smussles pecies most destined for consumption in Thailand. In total, 56 samples were examined from Bangkok (n = ...

The DNA of Cryptosporidium Oocysts was extracted from fecal samples by using Commercial Wizard Genomic DNA purification general kit, tow freezingthawing protocols have been compared in this study: deep freezer for three cycles and liquid nitrogen for fifteen cycles, the results indicate that the second protocol was more influential in obtaining a sufficient amount of DNA from Oocysts of Cryptos...

Isolates of Cryptosporidium spp. from human and animal hosts in Iran were characterized on the basis of both the 18S rRNA gene and the Laxer locus. Three Cryptosporidium species, C. hominis, C. parvum, and C. meleagridis, were recognized, and zoonotically transmitted C. parvum was the predominant species found in humans.

Cryptosporidiosis is a parasitic disease caused by Cryptosporidium spp. In immunocompetent individuals, it usually causes an acute and self-limited diarrhea; in infants, infection with Cryptosporidium spp. can cause malnutrition and growth retardation, and declined cognitive ability. In this study, we described for the first time the distribution of C. parvum and C. hominis subtypes in 12 child...

Newly available assays offer alternatives to conventional microscopic examination for Cryptosporidium spp. We compared two enzyme immunoassays, ProSpect Cryptosporidium microtiter assay (Alexon, Inc., Mountain View, Calif.) and Color Vue Cryptosporidium assay (Serady, Indianapolis, Ind.), and a direct immunofluorescent assay, Merifluor Cryptosporidium kit (Meridian Diagnostics, Cincinnati, Ohio...

Background. Rodents could act as reservoir for Cryptosporidium spp. specially C. parvum, a zoonotic agent responsible for human infections. Since there is no information about Cryptosporidium infection in rodents of Ahvaz city, southwest of Iran, hence, this survey was performed to determine the prevalence and molecular characterization of Cryptosporidium spp. in this region. Materials and Meth...

Little is known about the prevalence and genotypes of Cryptosporidium in fish. The present study investigated the prevalence of Cryptosporidium species in cultured fingerlings (n=227), wild freshwater (n=227) and wild marine/estuarine species (n=255) of fish in Western Australia by PCR amplification at the 18S rRNA locus. Results revealed a low prevalence of Cryptosporidium infection in fish ho...

A total of 238 pig fecal specimens were collected from pig farms in Corlu (Tekirdağ), Ayazma, and Arnavutköy (Istanbul) during the summer. Out of the 238 pig specimens, 105 were from pigs younger than 6 months and 133 from pigs older than 6 months. These were investigated for intestine parasites in particular the ones that are human pathogens. Cryptosporidium spp. was detected In 21 fecal speci...

To the Editor: Molecular tools are essential for Cryptosporidium spp. identifi cation, taxonomy, and epidemiology because of morphologic similarities between species within this genus. Molecular analyses have now identifi ed 22 Cryptosporidium spp. and >40 cryptic species (i.e., genotypes) across all vertebrate classes (1). The myriad of potential Cryptosporidium spp. hosts, in conjunction with...
